The relationship between aperture coefficient and shutter speed is

The aperture coefficient is proportional to the shutter speed.

A larger aperture factor (such as f/2.8) means that more light can enter the camera through the lens and hit the image sensor or film, thus increasing the exposure. A smaller aperture coefficient (such as f/ 16) allows less light to pass through, thus reducing exposure.

The shutter speed determines the length of time the camera lens is open. A slower shutter speed (for example, 1/30 seconds) allows more light to enter the camera, thus increasing the exposure. On the contrary, a faster shutter speed (such as11000 seconds) only allows light to enter the camera in a short time, thus reducing exposure.

Therefore, when more light needs to enter the camera to get higher exposure, you can choose a larger aperture coefficient and a slower shutter speed. When you need to reduce exposure, you can choose a smaller aperture coefficient and a faster shutter speed.

Aperture coefficient arrangement order:

Aperture coefficient (also called aperture value) is usually arranged according to relative size, and the order from large to small is: f/ 1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/1,f. Among them, a smaller aperture coefficient represents a larger aperture opening, which allows more light to enter the camera through the lens, making the image brighter and the depth of field shallower.

Circular coefficient and shutter speed are two important parameters in photography, which will affect the exposure of photos. Generally speaking, a larger aperture coefficient allows more light to enter the camera, making the image brighter, but it also leads to a shallower depth of field. Slower shutter speed can make the camera exposure time longer, capture more light, and make the image brighter, but it may lead to motion blur. Therefore, the choice of aperture coefficient and shutter speed should be balanced according to the specific situation in order to achieve the required shooting effect.
